2. Recent news
The activities on the second T300 module started on January 13, 2017.
The cathode has been removed. Flattening operations started and are expected to be completed by end of next week (by February 10, 2017). Additional 2 weeks are needed for polishing and electro-polishing. The cathode panels are expected to be back for re-installation at the end of February Re-installation is expected to be completed by first week of March.
All old cables and PMTs have been removed.
The new mechanical components for about 100 PMTs have already been cleaned and preassembled. All PMTs cables will be ready for installation (tested and cleaned) tomorrow. We expect to complete the assembly of the new PMTs by end of this month (February 2017).
The already pre-assembled decoupling boards are in Padova for reconditioning. The decoupling boards that have not been pre-assembled are under test (see A. Braggiotti presentation). A decision on how to proceed will be taken this Friday (February 3, 2017).
The installation of the new cables for the wires will take place during the last week of February.
